 OK, I see what is happening. See

 https://github.com/macports/macports-
 base/blob/master/portmgr/dmg/postflight.in#L281

 that is supposed to set DISPLAY to :0 only if on Tiger and if DISPLAY is
 not already set. The problem is the check for 'Tiger or less' is broken
 for macOS 11, as it just checks the minor version  < 4...

 I fix is needed in base for this.
